O.K. so I am another one of those that decided to put a supra engine in my pickup truck (84 xtra cab) so I don't really belong here but really am stuck and could use some help. The engine is a 5mge 85 or 86 (the engine has a knock sensor) The engine harness is from a year without the knock sensor but I know its not from an 82 because the distributor had no vacuum advance. My truck was original with a carb so I swapped the entire wiring harness in from the supra. Everything including the dash. I left the original truck ignition switch, wiper etc. When I try to start the truck the injectors do not fire. I have spark and the timing is right because it will run for a short while on starter fluid or gas. I have power to the ecu at the large plug. I can get the injectors to fire by jumping them at the plug that hooks up to the ecu. The injector resistor is good. My AFM is good when I push door fuel pump goes on. My circuit open relay clicks when I turn key. My EFI #1 and EFI#2 relays work. From what I understand this ECU fires by grounding them out when it gets a signal from the rotor inside the distributor. So if I have power at the ecu and power to my injectors and all the wiring is hooked up what is going on? Bad Ecu? not getting signal from distributor. I don't know. The ECU P/N is 89661-14020. it says 5mge M/T right on it. It plugs in fine, the only thing i notice is that where the ecu plugs go is orange and my plugs that go into it are a bannana yellow color. Is there a way to see if my ecu is bad or a way to make sure it is getting the proper signal it needs from the distributor? Any help would be great.
